Somebody just had major slappage sell/buy of 9531900 @ 13.  Either someone wanting to get out or a crew is getting ready to play some advancing technicals, imo.  But that is pinkie land, it is a poker game.  The "wager" is what an "opinion" is all about.  In Texas Hold 'em, I wager that my flush is, in my opinion, better than what you have in your hand, that three-of-kind that I cannot see and vice-versa.  So you place a bluff.  Telling me that you bought some shares today as "proof" of the veracity of your position.  My mama would slap me (for my own good)...lol
